Importers of Low-Density Polyethylene (LDPE) and Linear Low-Density Polyethylene (LLDPE), Specific Gravity Under 0.94 paid $3.4M in duties in July 2026 — an effective duty rate of 15% on $22.3M in dutiable value, based on actual customs collections rather than the published tariff schedule. Low-Density Polyethylene (LDPE) and Linear Low-Density Polyethylene (LLDPE), Specific Gravity Under 0.94 imports of $76.1M in July 2026 ran 30% above the year-to-date monthly average of $58.5M.
Polyethylene resins with a specific gravity below 0.94 — primarily low-density polyethylene (LDPE) and linear low-density polyethylene (LLDPE) — are foundational packaging and film resins used across flexible packaging, agricultural films, wire and cable insulation, and consumer goods. The US tariff schedule subdivides this heading into seven 10-digit lines distinguishing LLDPE, medium-density PE below 0.94, and high-viscosity grades (≥1.44 dl/g), among others. Canada is the dominant supplier, benefiting from USMCA treatment and integrated North American petrochemical supply chains, with Germany and Mexico also significant sources. Imports from South Korea may be eligible for preferential treatment under KORUS.

Polyethylene with a specific gravity of 0.94 or above classifies under a separate subheading (390120) covering high-density polyethylene. The 0.94 cutoff is measured on the resin in primary form; importers should obtain the manufacturer's technical data sheet confirming density to avoid misclassification, as LDPE and HDPE carry different duty treatment and are used in distinct downstream applications.
Tariff line 3901101000 covers polyethylene with a specific gravity below 0.94 and a viscosity number of 1.44 dl/g or greater — a specification associated with ultra-high-molecular-weight polyethylene (UHMWPE) used in industrial wear liners, medical implants, and ballistic protection. This grade commands a premium and may face different competitive dynamics than commodity LDPE or LLDPE film resins, making correct line-level classification important for duty and statistical accuracy.
